Hey folks, I ran into a similar memory leak issue. In my case a had the following:

for num in range(100):
    ds = xr.open_dataset('data.{}.nc'.format(num)) # This data was compressed with zlib, not sure if that matters

    # do some stuff, but NOT assigning any data in ds to new variables

    del ds

For some reason (maybe having to do with the # do some stuff), ds wasn't actually getting cleared. I was able to fix the problem by manually triggering garbage collection (import gc, and gc.collect() after the del ds statement). Perhaps this will help others who end up here...
